Subthalamic deep brain stimulation is an advanced therapy that typically improves quality of life for persons with Parkinson's disease (PD). However, the effect on caregiver burden is unclear. We recruited 64 persons with PD and their caregivers from a movement disorders clinic during the assessment of eligibility for subthalamic DBS. We used clinician-, patient- and caregiver-rated instruments to follow the patient-caregiver dyad from pre- to postoperative status, sampling repeatedly in the postoperative period to ascertain fluctuations in phenotypic variables...

Background and purpose: Stroke has been scarcely studied in Latin America (LA). The Mexican Institute of Neurology Stroke Registry was established in 1990 as a prospective computer-based database to register data obtained from patients admitted with stroke. Using this data, we attempted to define the profile of risk factors and outcomes. Methods: The demographic data, stroke description, ancillary tests, vascular risk factors, and modified Rankin scale (mRs) were registered...

A 26-year-old man with history of extensive tophaceous gout presented to the referring facility with decreased bilateral lower extremity sensation and motor function that began acutely 1 week prior to admission and had progressed to urinary incontinence. The patient was admitted to the intensive care unit due to concern for sepsis secondary to epidural abscess. The patient was started on empiric vancomycin and cefepime. Neurosurgery did not recommend acute neurosurgical intervention given the lack of a compressive lesion...

BACKGROUND: The association between underlying liver disease and poor surgical outcomes has been well-documented across a wide variety of surgical disciplines. However, very little is known about the importance of liver disease in neurosurgery. Here, we assess the independent effect of liver disease on perioperative outcomes in patients undergoing craniotomy for tumor. METHODS: The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was queried for patients undergoing craniotomy for tumor from 2006 to 2015...

Polymethylmethacrylate (PMMA) is the most commonly used filler material that lacks biological properties and osteoconductivity or osteoinductivity. Platelet gel (PG) is a typical source of growth factors, cytokines and molecules efficient for bone formation and remodeling. The aim of this study was to evaluate bone healing and regeneration of bone defect in rat model by combining PMMA with PG. A total of 50 defects were created in the diaphysis of the radii of 25 male Sprague-Dawley rats. These defects were randomly divided into five groups (n = 10 defects for each group) and treated by autograft, plain PMMA, PG and PMMA-PG or left untreated...

Rehabilitation for people with spinal cord injury in many low- and middle-income countries is not avail-able or is in the early stages of development. However, rehabilitation is recognized as crucial in order to optimize functional recovery and outcomes for patients with spinal cord injury. With an increasing incidence of spinal cord injury, the unmet need for rehabilitation is huge. This report describes the early development of a specialist rehabilitation service for spinal cord injury in Madagascar, one of the poorest countries in the world...

We present an analytical review of various neurosurgical interventions in conscious patients. An analysis of the literature indicates growing interest in this problem. Craniotomy in conscious patients has been extensively used in resection of space-occupying cerebral lesions in the eloquent hemispheric areas and in epilepsy surgery. In recent years, there have been a number of reports on interventions in conscious patients with other neurosurgical pathologies, which may be regarded as a new emerging tendency in neurosurgery and neuroanesthesiology...

Introduction Medical education involves training necessary to become a physician or a surgeon. This includes various levels of training like undergraduate, internship, and postgraduate training. Medical education can be quite complex, since it involves training in pre-clinical subjects (anatomy, physiology, biochemistry), the para-clinical subjects (microbiology, pathology, pharmacology, and forensic medicine), and a discrete group of clinical subjects that include general medicine, surgery, obstetrics and gynaecology, ear, nose and throat specialization, paediatrics, cardiology, pulmonology, dermatology, ophthalmology, and orthopaedics, and many other clinical specializations and super specialities (cardio-thoracic surgery, neurosurgery, etc...

The application of electrical stimulation mapping (ESM) of the brain for clinical use is approximating a century. Despite this long-standing history, the value of ESM for guiding surgical resections and sparing eloquent cortex is documented largely by small retrospective studies, and ESM protocols are largely inherited and lack standardization. Although models are imperfect and mechanisms are complex, the probabilistic causality of ESM has guaranteed its perpetuation into the 21st century. At present, electrical stimulation of cortical tissue is being revisited for network connectivity...

OBJECTIVE The authors present long-term follow-up data on patients treated with Gamma Knife radiosurgery (GKRS) for acoustic neuroma. METHODS Six hundred eighteen patients were radiosurgically treated for acoustic neuroma between 1992 and 2016 at the Department of Neurosurgery, Medical University Vienna. Patients with neurofibromatosis and patients treated too recently to attain 1 year of follow-up were excluded from this retrospective study. Thus, data on 557 patients with spontaneous acoustic neuroma of any Koos grade are presented, as are long-term follow-up data on 426 patients with a minimum follow-up of 2 years...

OBJECTIVE There are numerous treatment strategies in the management for large vestibular schwannomas, including resection only, staged resections, resections followed by radiosurgery, and radiosurgery only. Recent evidence has pointed toward maximal resection as being the optimum strategy to prevent tumor recurrence; however, durable tumor control through aggressive resection has been shown to occur at the expense of facial nerve function and to risk other approach-related complications. Through a retrospective analysis of their single-institution series of keyhole neurosurgical approaches for large vestibular schwannomas, the authors aim to report and justify key techniques to maximize tumor resection and reduce surgical morbidity...

BACKGROUND: Artificial Intelligence (AI) techniques play a major role in anesthesiology, even though their importance is often overlooked. In the extant literature, AI approaches, such as Artificial Neural Networks (ANNs), have been underutilized, mainly being used to model patient's consciousness state, to predict the precise amount of anesthetic gases, the level of analgesia, or the need of anesthesiological blocks, among others. In the field of neurosurgery, ANNs have been effectively applied to the diagnosis and prognosis of cerebral tumors, seizures, low back pain, and also to the monitoring of intracranial pressure (ICP)...
